To all whom it may concern:

' Beit known that I, WILHELM SAssAcKQof the city, county, and State of New York, have invented a new and usefull Improvement in Smoothing-Machines, which improvement is fully set forth in the following'speciiication,

reference being had to thel accompanying drawings, in which- 4 Figure l shows my machine partly in top view and partly in horizontal section,tl1`e plane of section being indicated by the linea: fr, Fig. 2. Fig. 2 is a longitudinal `vertical section thereof in 4the plane of the line` y y, Fig. 3. Fig. 3 is a cross-section of the same in the plane of the line z z, Fig. 1. Fig. 4 is an inverted plan -view of the smoothing-head.

Similar letters indicate corresponding parts.

My invention relates to machines for smoothing the surfaces of veneers-as, for example, those used for piano-tops and other articles, whether of wood or other material.

In the drawings, the letter A designates a head, constitutingt-he part whereby the smoothing is effected, and B is a bed for `supporting the veneer or other article to be acted on. The smoothing-head A rests on the bed B, or the article placed thereon, by its own weight and that of a frame, O, which is constructed with horizontal ways d, with which the smoothinghead is arranged to engage, so that the headA is capable of a horizontal reciprocating motion, and isk guided therein by the frame C. The bed B is movable and rest-s on'parallel guideways B. The guide-frame C is arranged between two standards, E E, connected at the top by a cross-piece, E', and it engages these standards by vertical tongues and grooves, as at f, Fig. 1, so that the guide-frameisadapted to be moved up and down between the standards, whereby the smoothing-head Abecomes lifted up from the bed B or lowered thereon.

For the purpose of moving the guide-frame` mechanism for imparting thereto a'reciprocat ing motion, consisting of a crankshaft, I, which has its bearings in arms J projecting from the standards EE, and connects with the smoothing-head A'by means'of a bifurcated ma, k. `Themank-Shaa I carries a fast and. loose-pulley, Z and l,' and is geared by abelt, n, with a 'shaft,0, carrying a pinioinp, which Lis arranged in such relation to racks q q', both fastened to the bed B, that-by a longitudinal movement of the shaft O the pinion is thrown in gear'with either of the racks, whereby the bed obtains reverse motions on the ways B. Any other suitable reversing-gear, however, may be substituted for the racks and pinionas, for example, the reversing-gear used in `metal-planing machines; or the bed may be left stationary. p

The smoothing-head A consists of a series of stone blocks, s, a back, t, and a series of yokesga, one to each block. The stone blocks s are shaped to interlock with each other, and in this example they are made of a substantially T shape, as shown in Fig. 4; but it is obvious that the desired object can be attained with a variety of othershapes.

The back t is the part whereby the smoothing-head engages the guide-frame G and connects with the crank-shaft I, and the yokes u embrace the back, as shown in Fig. 2, while they are bent toward each other at their exs, fitting loosely into horizontal grooves in the latter, so that while the blocks are firmly supported onl the back t by the yokes they are Vtremities, where they grasp the stone blocks l permittedto rise independently of the back,

and thus readily adapt themselves to any sinuosities in the surface of the article passing through the machine. Y

Each of the stone blocks s has an eye, o, which extends through the block from top to bottom, so that a suitable quantity of polishing or smoothing material, as pumice-stone, may be introduced to the eyes, whence it falls and is distributed on the surface acted upon by the blocks. Y

To facilitate the distribution of the smoothing material by the stone blocks '8, they are provided with channels in their lower surfaces,

radiating from the eyes o, as clearly shown.

For the purpose of introducing the smoothing material to the eyes v of the stone blocks.

IOO

The vencer or other article is placed on the bed B, and then the crank-shaft I is set in motion, when the smoothing-head A obtains a reciprocating movement on the surface ofthe veneer, while the latter, at the same time, is caused to advance and recede by the reversing-gear, so that the entire surface of the veneer is subjected to the action of the smoothin g-head, whereby it is uniformly smoothed or polished.

What I claim as new, and desire to secure by Letters Patent, is

1. In a smoothing-machine, the combination I nation with mechanism for imparting a recprocatingmotion to thesmoothing-head, aframe adapted to guide the smoothing-head, a hed for supporting the article to be smoothed, and reversing-gear acting on the bed, the whole being adapted to operate substantially as described.

3. A smoothing-head consisting of' a series .of stone blocks shaped to interlock with each other, and having eyes for the reception of smoothing material, aback carrying the stones, and a series of funnels passing through the hack and into the eyes of thel stones, in con:- bination with mechanism for imparting a reciprocating motion to the smoothing-head, a frame adapted to guide the smoothing-head, a bed forsupporting the article to be smoothed, and reversing-gear acting on the bed, the Whole being adapted to operate substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 5th day of December, 1879.
